Benefits of technology
The solution effectively prevents gas leaks by maintaining a stable connection between the combustor and turbine, ensuring efficient operation and reducing the risk of gas leakage.
Problems solved by technology
The combustor supplies fuel to compressed air that is compressed in the compressor and ignites the air with a burner, which results in generation of combustion gas of high temperature and high pressure.
In this case, a gap may be created at the contact portion of the conjunction assembly meeting the turbine inlet cylinder constituting the inlet of the turbine, as a result, gas may be leaked between the combustor and the turbine.

Embodiment Construction
[0024]Hereinafter, embodiments of a conjunction assembly and a gas turbine comprising the same according to embodiments of the present disclosure will be described with reference to the drawings.
[0025]Referring to FIG. 1, an example of a gas turbine 100 to which a conjunction assembly according to the present disclosure is applied is shown. The gas turbine includes a housing 102, and a diffuser 106 is provided on a rear side of the housing 102 to discharge a combustion gas passing through the turbine. A combustor 104 for burning compressed air that is supplied from the compressor to is disposed on the front side of the diffuser 106.
[0026]The description will be made with reference to a flow direction of air. A compressor section 110 constituting the compressor is positioned upstream within the housing 102, and a turbine section 120 constituting the turbine is positioned downstream within the housing 102. A torque tube 130 is positioned between the compressor section 110 and the turb...

A conjunction assembly provides a seal, in a connected state, between a conjunction ring constituting an outlet of a combustor and a turbine inlet cylinder constituting an inlet of the turbine. The conjunction assembly includes a connecting member that protrudes from the conjunction ring; a connecting groove for receiving the connecting member, the connecting groove formed in the turbine inlet cylinder; and a connection sealing member disposed between the connecting member and an inner surface of the turbine inlet cylinder to provide a seal between the connecting member and the inner surface of the turbine inlet cylinder. The connecting member is a ring-like structure formed on a rear-side surface of the conjunction ring, the rear-side surface facing the turbine inlet cylinder, and the connecting groove is formed in a front-side surface of the turbine inlet cylinder in correspondence to the connecting member, the front-side surface facing the conjunction ring.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Korean Patent Application No. 10-2017-0127459, filed on Sep. 29, 2017, in the Korean intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTIONField of the Invention[0002]Exemplary embodiments of the present disclosure relate to a conjunction assembly and a gas turbine comprising the same, and more particularly to a conjunction assembly for providing a seal, in a connected state, between a conjunction ring constituting an outlet of a combustor and a turbine inlet cylinder constituting an inlet of the turbine, and a gas turbine comprising the same.Description of the Related Art[0003]A turbine is a mechanism that obtains rotational force by impulsive force or reaction force generated using a flow of compressible fluid such as steam or gas. Examples of the turbine include a steam turbine using steam and a gas turbine using high temp...
